Fortranコンパイラの自動並列化性能評価

We carried out a series of benchmark tests to know the ability of automatic parallelization of four Fortran compilers : SPARC Fortran 77, C ray Fortran 90, Apogee Fortran 77 and Apogee Fortran 90. We aimed to select the best compiler at the time of Operating System version up in the EIC computer. These tests revealed that the best is Apogee Fortran 77, and the worst is Cray Fortran 90 among them. Then we installed the Apogee Fortran 77 and Apogee Fortran 90 in the new-OS instead of Cray Fortran 90. After the new-OS was installed, we again carried out the same benchmark tests for Apogee Fortran 77, Apogee Fortran 90 and SPARC Fortran 77 Ver. 4.0 under the new-OS. The results showed that SPARC Fortran 77 (Ver. 4.0) is generally better than Apogee Fortran 77 and that Apogee Fortran 90 is the best for solving a linear equation.＜論説
